A function in math is a rule or relationship between two sets of numbers, where each input value (or x-value) is associated with exactly one output value (or y-value). In simpler terms, a function assigns each input value to exactly one output value.
In the given table, the "Day of the week" is the input value and the "Number of children in the car" is the output value. Each day of the week is paired with a specific number of children in the car, and each day only has one corresponding number of children. This demonstrates that each input (day of the week) is associated with exactly one output (number of children in the car), making it a function.
Describe the meaning of a function in math. Then consider the table, why does this table show a function?
